Vulcanizing Agents of Rubber

 Vulcanization is a chemical process that is used to improve the properties of both natural and synthetic rubber. Sulfur is the most common vulcanizing agent in rubber. When rubber is heated in the presence of sulfur, accelerator, and activator at 140–160°C, the formation of crosslinks long rubber molecules are formed. At the end of vulcanization, we achieve the rubber with improved elasticity, resilience, tensile strength, viscosity, hardness, and weather resistance.



Often a catalyst and initiator is added to accelerate the vulcanization process. These cross-linked elastomers (vulcanized rubber have much better mechanical characteristics), made it possible to turn rubber into something that can help us in our daily life. Unvulcanized rubber has poor mechanical properties and is not very durable that's why using a vulcanizing agent in rubber is a must. OCCL India provides some of the best grade sulfur and insoluble sulfur that are the most important raw material for the tyre industries.

What Is Sulfur Blooming?

Image
 Rubber is the main raw material in the manufacturing of tires. Industry uses both natural and synthetic rubber for the purpose. To maintain the quality of rubber sulfur content is one of the most important parameters.  Raw rubber is a hydrocarbon in nature and is a thermoplastic. In order to eliminate the undesirable property of malodorousness, treating rubber with sulfur, other accelerators, and antioxidants are necessary. Which in turn helps to prolong the life of rubber product tires in this case.  However, being crystalline organic sulfur is somewhat soluble in polymers (rubber). Mixing ordinary sulfur to the natural rubber will be of no use as it will dissolve during the hot mixing process. Later after cool-down, it will form the crystallized surface, causing the sulfur to bloom. This might not affect the function of the rubber product but it will mess up the appearance of the product.  To prevent this undesirable effect of sulfur blooming , insoluble sulfur is used in Rubber.

What Is Rubber Blooming And How To Prevent It?

Image
 The crystallization of compounding ingredients that are usually present on the surface of stock, cured or uncured, are always accompanied by the migration of the substance from the bulk to the surface, this phenomenon is known as Blooming. Any ingredient which is soluble in rubber can undergo blooming. These additives are soluble in rubber at high temperature but when cools down it decreases the solubility which leads to the migration to the surface. Blooming results in reducing the thickness of the stock, which is not ideal in the manufacturing of the tires and belts. How To Prevent Blooming In Rubber? Sulphur blooming is one of the major issues tackled by the rubber industry using the insoluble sulphur. To complete the process while avoiding sulphur blooming, the insoluble sulphur is mixed in the compound and the processing temperature is kept below the transition point of sulphur.  That’s why insoluble sulphur is one of the most important components in the rubber industry.

Insoluble Sulfur And Properties It Offer To Rubber Manufacturing

Image
 Rubber and rubber components are widely used in all parts of the world, in various forms. Most of the time we don’t even notice them, but they have a big impact in simplifying our daily lives. However it will be very difficult to form rubber into what we are using today without the help of insoluble sulfur . Known as the best vulcanizing agent among the rubber manufacturers, insoluble sulfur is what helps to prevent blooming in rubber.  As we can not use the natural rubber due to its lack of characteristics, that’s why treating it with other chemicals under vulcanization helps rubber manufacturers to produce synthetic rubber with better characteristics, more tensile strength and improved resistance to heat and oxidation. However, storing insoluble sulfur compounds can get tricky, as it is an unstable chemical that reverts into rhombic sulfur at room temperature. That’s why it is necessary to maintain the desired environment. Or use other better grade insoluble sulfur such as crystex H
